The development of fluidized bed combustion (FBC) systems, which enable an industrial user to burn a range of inexpensive fuels, such as high sulfur coal, without installing scrubbers, has simultaneously hastened the introduction of microprocesser-based controls to provide automatic operation of the equipment. In addition to the combustor itself, FBC coal firing requires several sizeable auxiliary systems, such as fuel, limestone and ash handling. Sophisticated control subsystems integrate the various aspects of the FBC installation into an efficient, easily operable system. This article details the use of a microprocessor-based control being used at a meat packing and rendering plant to regulate a 70,000 lb/hr coal-fired combustor, which cogenerates 1250kw of electric power and provides all heating and process steam requirements. A mix of sequence and PID controls regulate steam-drum pressure, coal and limestone feed rate, coal drying, secondary air, draft and drum level.
